ok currently i have 2 choice either b18c or b18a/b block for turbo

My problem is i already bought rods and piston for b18c but my workshop told me that they couldnt get b18c but b18a /b so will the rods and piston fit in b18a /b and whats the different between b18a/b and b18c.The mechanic told me there is no difference at all

I'm a little confused as to what you are asking (late night maybe) but tell you mech that there are quite a few differences between the B18b and the B18c.

GSR rods are longer than LS rods, they won't work. Pistons will work. Tell the guys at the shop to go fist themselves and get you what you originally asked for. Better yet, go take your business somewhere else because if they think there is no difference between a B18A/B18B and a B18C they're idiots that I wouldn't trust to even look at my car.

 

^^^I agree with this guy, if the shop think there is no difference between the b18c and the b18a/b then I would not let them touch my car.

The pistons are interchangeable, because all b16a's,b18c's, and b18a/b's have an 81mm bore from the factory.

To be honest, I did not know that the GSR rods were longer, I thought the LS rods were longer...but anywhoo, if the GSR rods are really longer than its a no-can do. However, if it turns out that I am right and the LS rods are longer, than you can still use the GSR rods, you would just have to re-deck the block to make the GSR rods work.

The LS has a longer stroke than the GSR so you were right.

 

i were told that b18a/b block use back the crank stroter and rods of b18c the mech said that it is basically same with b18c

I'll tell you what. I'm guessing you arn't pressed for time. Instead of trying to blast out this post in 10 seconds or less, take 30, maybe even 45 seconds and used PUNCTUATION and GRAMMAR to form a readable sentence. I do not have a clue what you're trying to say here. It makes it incredibly hard for people to help you when they don't even know what you're asking or saying.

When I thought the LS rods were longer this was the reasoning I used
Thanks for helping me clear this up. So if this is the case, the GSR rods can be used with the b18a/b block, but you will have to re-deck the block to the correct level of the pistons at TDC(Top-Dead-Center).

Don't be too harsh man. But I agree with turboEGsedan, try to clean up the grammar a bit, I am having trouble understanding you as well.

The GSR rods are longer AND the big end is narrower!!You can use the GSR rods and crank in the LS block,or the LS rods and crank in an GSR block.The LS crank and GSR rods will put the piston above the deck,so decking the block sure won't help.The GSR stroke is shorter,the piston is the same as the LS,so the rod has to be longer than the LS .The blocks are the same height.
